PENFS improved oral intake, weight, and other anthropometric measures in addition to GI and psychological measures in patients with FD. Changes in anthropometrics were sustained at 3-month follow up. PENFS may be an effective treatment for patients with FD, including children, and restrictive eating to optimize nutritional outcomes. Future studies should include prospective clinical trials and investigate the mechanism of action of PENFS on eating habits.
